Mode three: the power of LED lamp bead is different, is positioned at middle power less, gradually large to both sides power, it is 2A that the rated current of all LED lamp bead is added total current.
Adopt the technical program, the operating current after all LED lamp bead are connected in parallel is 2A, therefore can use the USB power source of current usual widely used SELV 5V easily.
Adopt the angle within the scope of above-mentioned α, β, and the length that limits of related work parts LED lamp panel, reflector, vertical rod and physical dimension, can realize and meet the related request of national standard " read and write operation post lamp behaviour requirement " GB/T 9473-2008.
Standard GB/T/T9473-2008 " read-write operation post lamp behaviour requires " mainly contains the requirement of light-proofness and illumination and the uniformity thereof in light measurement requirement.Wherein light-proofness requires: eyes, apart from the height 400mm of read-write desktop, from the horizontal range 600mm place of light source center, are looked towards lamp, should be can't see reflector inwall and light source.
Further, described lampshade is fixed in vertical rod in snakeskin hose mode.
Further, described LED lamp bead is 3-6cm to the horizontal range L of described vertical rod.
Further, described LED lamp bead is fixed in LED lamp panel with welding manner.
Further, described α is 102 °, described β is 38.6 °, and the width D of described reflector 7 is 18mm, and the height H of described vertical rod 2 is 40cm.
Further, described reflector is that aluminium sheet, corrosion resistant plate or hard plate post reflective membrane.
The beneficial effects of the utility model.
The utility model has the advantage of; the lamp holder that this LED reads and writes visual task desk lamp uses the USB power source (SELV) of 5V to power; safer; and existing charger for mobile phone/power supply adaptor or other every power electronic equipment with USB output port can be used; power supply mode is various, flexible, to reduce electron wastes, and protection of the environment; economize on resources, reduce use cost.
Being skillfully constructed of this lamp holder, doubles as radiator owing to having used printed substrate, and radiating effect is better, and cost greatly reduces, and largely solves the problem that LED lamp holder weak heat-dissipating, luminance decay are too fast;
Structure is simple, assemble laborsaving saving time; The main light measurement performance such as illumination and uniformity of illuminance meets the related request of national standard " read-write operation post lamp behaviour requires " (GB/T 9473-2008).
