Description

LED light fixture

The present invention provides an LED luminaire technology that can illuminate the lighting characteristics of a tungsten-like bulb, and the diameter thereof has the advantages of good heat dissipation, good light extraction rate, and substantial economic progress.

For example, in the case of car lights, in order to take into account the driver's driving and pedestrian safety, the luminous efficiency and light shape of general vehicle lamps must meet the relevant safety regulations.

When the conventional tungsten filament bulb is equipped with the lamp, it uses the tungsten wire to produce the light shape and brightness according to the regulatory standards; however, the tungsten filament bulb consumes a large amount of electricity, generates high heat energy when emitting light, and has shortcomings such as short service life. Therefore, it has gradually been replaced by LED; however, although LED has the advantages of high brightness, power saving, environmental protection and durability, LED is a certain direction to emit light, so that the illumination angle used in the lamp can not be effectively improved, although it can be utilized more LED distribution and different angle configurations are achieved, but they are derived from increased manufacturing costs, and these LED light sources are prone to optical dispersal and concentration.

Therefore, the latest patent case of M468624 "Tungsten-like LED Bulb Structure" came into being, but the patent has at least the following shortcomings:

First, the heat dissipation is not good: its LED is covered by the lampshade, these The sealed or semi-closed space will gradually accumulate the heat generated by the LED, because 65% of the input power of the LED will be converted into heat, and the heat accumulated in the sealed or semi-closed space will reduce the LED efficiency and will make the LED The life is shortened. Generally speaking, the life of an LED is about 100,000 hours. However, if the operating temperature is higher than 85 ° C, it will be greatly reduced. Especially when the reflective element abuts against the LED, the heat storage disadvantage is more obvious.

Second, the manufacturing cost is high: it consists of a left lamp housing, a right lamp housing, a joint portion and a reflecting element to form a lampshade. The components are not only complicated but complicated, and the assembly is quite time-consuming and laborious, and does not meet the economic benefit appeal.

Third, the light output rate is not good: because the reflective element is abutting on the LED, causing the reflective element to be projected by the LED light source, and a predetermined light shape distribution occurs, a large part of the light shape is obscured by one end of the base Therefore, there is still room for improvement in its light output rate.

Therefore, the creator has carefully researched and improved, and after years of experience in this industry, he developed this new type.

The present invention provides an LED lamp comprising at least: a base; an LED module mounted on one end of the base; a reflector having a reflective curved surface; and a rod holder having a reflector suspended The shank is mounted on the pedestal to maintain a fixed distance between the reflective curved surface and the LED module, and forms a heat dissipation space around the vacant space. When the LED module is powered to generate a light source, the reverse The curved surface is directly projected by the light source to generate a preset light distribution for illumination.

Therefore, the novel can simplify the left lamp housing, the right lamp housing and the joint portion of the above patents into a single pole frame. This configuration has the advantages of light weight, simplified structure and improved assembly efficiency, so that the present invention is economical. It has a long gain. More importantly, in addition to the heat conduction of the LED module by the pedestal, the present invention is configured to transmit air convection to the surrounding environment through a fixed spacing and a heat dissipation space. This dual heat dissipation mechanism and performance can be as far as possible. Maintain the life of the LED module. Furthermore, the arrangement of the fixed pitch and the heat dissipation space can also reduce the shielding of one end of the base to achieve the advantage of increasing the light extraction rate. Therefore, this new model can indeed improve many problems in the above-mentioned patents, and the substantive effects are improved.
