Abstract

The utility model relates to an energy saving ceiling lamp, and the inside of insulation shell is in orders provided with a step down transformer, a rectifier and a current limiting resistance after connected with electricity. The upper part of the insulation shell is connected with lamp head, and the lower part is connected with the concave disk and the transparent protection cover. The central plane and concave side of the disk are respectively provided with a reflection shield. The utility model is provided with white LED group with high brightness. The LED has the advantages of high brightness, low energy consumption and long service life. The utility model adopts the combination of a plurality of pipes, which focuses on the reflection shield, so the utility model increases lighting brightness and lighting are under the effect of reflection. The utility model not only saves power energy, but also can meet the lighting requirement for life, reading and writing.

Description

A kind of energy-conserving pendent lamp

Technical field

The utility model belongs to ligthing paraphernalia, relates to a kind of energy-conserving pendent lamp.

Background technology

The domestic energy-saving lamp, for its power of using electricity wisely is generally in the 12W, brightness is lower, particularly during peak of power consumption, and dim light, only can be as general low-light level illumination, more, fragile owing to used electronic original part simultaneously, the easily aging blackening of fluorescent tube, much more very the needs of aspect such as can't satisfy reading, write bring difficulty to the user.

Summary of the invention

For solving the shortcoming of using the low power energy-saving lamp luminance shortage because of economize on electricity, the utility model provides a kind of energy-conserving pendent lamp of being made up of high brightness white hair optical diode, and not only power saving can provide enough brightness of illuminations simultaneously when voltage is low.

The technical scheme that its technical problem that solves the utility model adopts is: on a spill disk, by certain distance several high reflection shields are set, a high brightness white hair optical diode is installed in each reflection shield, its power supply by civil power through the transformer step-down, rectification is supplied with after the current limliting, and whole element is assembled in after being electrically connected in the insulation crust, the bottom of insulation crust is connected with the spill disk, and top is connected with a lamp holder.

Characteristics such as high brightness white hair optical diode has the high and low energy consumption of brightness, the life-span is long, response speed is fast, volume is little, but its light source becomes light beam irradiates after the convex surface at top focuses on, its illuminated area is less, after high brightness white hair optical diode is installed in the reflection shield of spill disk, the light of every luminous tube is being focused on, under the reflective effect, not only increase brightness of illumination and enlarged lighting area simultaneously effectively.

After the power transformer step-down, city's power supply and working power are isolated, guarantee that high brightness white hair optical diode works in the low-voltage DC supply state all the time, and guarantee the safety that human body contacts with it, while is owing to city's voltage and operating voltage is bigger, the variation of city's voltage is very little to the operating voltage influence, thereby has guaranteed brightness of illumination, the needs that can satisfy life, read, write etc. throws light on.

Electricity-saving lamp and the utility model contrast are as follows

Supply voltage: 220V, overhead height: 2.5M

Electricity-saving lamp: 12W power consumption: 12W effect: can't see No. five small characters of books and newspapers clearly.

This example: 31 of luminous tubes, voltage: 220V through step-down rectifier to 6V, every current limliting 15mA,

Power consumption: about 5W.Effect: No. five small characters can seeing books and newspapers clearly.

Compare with commercially available electricity-saving lamp, but the utility model power saving is over half, save the many electronic original parts on the electricity-saving lamp simultaneously, utilize the high and low energy consumption of high brightness white hair optical diode brightness characteristics, guaranteed brightness of illumination, the illumination needs that can satisfy life, read, write etc.

The beneficial effects of the utility model are, because high brightness white hair optical diode has characteristics such as the high and low energy consumption of brightness, life-span length, adopt the combination of number pipe, and under the high reflection shield effect of matrix disk, increase brightness of illumination, enlarge lighting area, because city's voltage and operating voltage is bigger, the variation of city's voltage is very little to the operating voltage influence, thereby has guaranteed brightness of illumination, saves energy not only can satisfy simultaneously and live and the needs that throw light on such as read, write.
