Description

A kind of LED bulb

Technical field

The utility model relates to the lighting apparatus field.

Background technology

Energy shortage is the hot issue of the world today, and in illuminating industry, led light source is because multiple advantages such as its efficient, energy-saving and environmental protection, long-life are to replace the energy consumption height, the first-selection of the traditional lighting that the life-span is short.Existing LED bulb is made of lamp holder, lamp housing, Transparent lamp shade and led light source, and wherein the chip of led light source all is to be encapsulated on nontransparent substrate, and the most frequently used nontransparent substrate is exactly an aluminium base.The defective of existing product is that chip is encapsulated in the last beam split of nontransparent substrate and is blocked by nontransparent substrate, and the emission angle maximum of light also has only 180 degree, and the utilization rate of light is low, and the single and structure production cost that adopted aluminium base of structure is also than higher.

Summary of the invention

Goal of the invention of the present utility model is the low problem of utilization rate for the light that overcomes existing LED bulb existence, provides a kind of utilization rate height of light, novel structure, the LED bulb that production cost is low.

In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:

A kind of LED bulb comprises lamp holder, lamp housing, Transparent lamp shade and led light source, and lamp housing is installed on the lamp holder, and Transparent lamp shade is installed on the lamp housing, and led light source is arranged in the lamp housing, and Transparent lamp shade covers on outside the led light source; Described led light source comprises substrate, chip, support, gold thread and fluorescent material, and chip is connected by gold thread with support, and chip is encapsulated in the substrate, and described substrate is a transparency carrier, and transparency carrier is provided with inner groovy; Fluorescent material is divided into phosphor powder layer and following phosphor powder layer, and last phosphor powder layer is located at the chip top, and following phosphor powder layer is located at the chip below; Last phosphor powder layer, chip and following phosphor powder layer are encapsulated in the inner groovy of transparency carrier.

As preferably, described phosphor powder layer, chip and the following phosphor powder layer gone up is encapsulated in the inner groovy by insulating cement.

As preferably, described transparency carrier is transparent organic glass or transparent inorganic glass, and described transparent inorganic glass is a pebble glass.

As preferably, described inner groovy is in-line.Further, transparency carrier is one, inner groovy on it is one, chip in the inner groovy is the polylith that is arranged in parallel, because chip be encapsulated in the transparency carrier can 360 degree luminous, many of transparency carriers or inner groovy are a plurality of to be the relatively waste that can interlock of light that chip sends, adopts the utilization rate height of said structure light.

As preferably, the operating voltage of described chip is 6V-12V, popularizes convenient the use the most.

As preferably, described led light source is connected with lamp holder by constant-current supply, good stability.

A kind of LED bulb by the technique scheme design, substrate on the led light source is a transparency carrier, chip 360 degree is luminous all can to penetrate transparency carrier, light transmission and can not being blocked arbitrarily, the utilization rate of light is more than doubled, and reduces greatly with respect to traditional aluminium base structure production cost.Fluorescent material is regulated the color of the light that led light source sends because chip be encapsulated in the transparency carrier can 360 degree luminous, so need fluorescent material be set respectively in the above and below of chip.It mainly is to be convenient to encapsulation that chip and fluorescent material are encapsulated in the inner groovy of transparency carrier.The advantage of this LED bulb is a novel structure, the utilization rate height of light, and production cost is low.

The specific embodiment

Be described further below in conjunction with accompanying drawing 1, Fig. 2 and Fig. 3 the utility model.

As Fig. 1, Fig. 2 and a kind of LED bulb shown in Figure 3, constitute by lamp holder 10, lamp housing 11, Transparent lamp shade 12, constant-current supply and led light source 9.Lamp housing 11 is installed on the lamp holder 10, and Transparent lamp shade 12 is installed on the lamp housing 11, and led light source 9 is arranged in the lamp housing 11, and Transparent lamp shade 12 covers on outside the led light source 9, and led light source 9 is connected with lamp holder 10 by constant-current supply.

Led light source comprises by substrate 8, chip 4, support 1, gold thread 2 and fluorescent material and constituting.Substrate 8 is transparency carriers, and transparency carrier 8 is provided with inner groovy 3.Chip 4 is connected by gold thread 2 with support 1.Fluorescent material is divided into phosphor powder layer 6 and following phosphor powder layer 7, and last phosphor powder layer 6 is coated in chip 4 tops, and following phosphor powder layer 7 is coated in chip 4 belows, and last phosphor powder layer 6, chip 4 and following phosphor powder layer 7 are encapsulated in the inner groovy 3 of transparency carrier by insulating cement 5.

Transparency carrier is to be of rectangular shape, and the inner groovy 3 on it is one, and inner groovy 3 is in-line, and the chips 4 in the inner groovy 3 are 2 rows that are arranged in parallel, and polylith chip 4 is all arranged on every row, are connected in parallel on the support 1 by gold thread 2.Lamp housing 11 is inserted in the bottom of support 1 fixes led light source, and the effect of support 1 is support fixation, conduction and heat radiation.Chip 4 be encapsulated in the transparency carrier can 360 degree luminous, transparency carrier is that many or inner groovy 3 are the relatively wastes that can interlock of light that a plurality of chips 4 send, adopts the utilization rate height of said structure light.

Above-mentioned transparency carrier is a transparent inorganic glass, wherein adopts pebble glass effects the best, because pebble glass fusing point height, translucent effect is good.The operating voltage of chip 4 is between 6V-12V, popularizes convenient the use the most.The Transparent lamp shade of common bulb is inner need to be sealed and vacuumize, and does not need to vacuumize in the Transparent lamp shade 12 of this patent.
